More Information
Summary:A valve assembly (32) is provided that automatically dispenses aerosol conte nt from a can (22) at predetermined intervals. A diaphragm (70) at least partially defines an accumulation chamber (71) that receives aerosol content from the can (22) during an accumulation phase. Once the internal pressure o f the accumulation chamber (71) reaches a predetermined threshold, the diaphra gm (70) flexes to initiate a spray phase, during which the aerosol content is delivered from the accumulation chamber (71) to the ambient environment. A rotatable pawl (78) provides resistive pressure and control of diaphragm movement.
